Abstract： |
The relates to the prevention of channel package losing in audio code transmission, featuring in the BCH encoding for each audio parameter for barrel shape displacement superposition, packing and channel transmission. At the decoding end, it receives interfered audio data package for Berlekamp deciphering, based on the corresponding deciphering ability to record its result, circulating to the completion of the package deciphering. Reviewing deciphering data of each group, overlaps most judgment together with sound parameter error treatment and combined for sound decoding. It can improve the synthesized sound quality with less bandwidth consumption. |
